What Is a Biogas Holder Membrane?
A biogas holder membrane is a reinforced, gas-tight technical fabric used to store or contain biogas in low-pressure flexible gas storage systems.
Used for Flexible Biogas Storage
Biogas holder membranes are used in double membrane gas holders, biogas domes, biogas balloons, single membrane holders, digester membrane roofs and tank-mounted gas storage covers. They help store methane-rich biogas before it is used for CHP, heating, upgrading, electricity generation or process energy.
Different Membranes Have Different Jobs
In a double membrane system, the inner membrane typically holds the biogas while the outer membrane maintains shape and protects against wind, rain, UV and weather loads. In a dome or balloon system, a bottom membrane may also be used as part of the gas storage envelope.
Biogas Holder System Types DERFLEX Membrane Can Support
DERFLEX biogas holder membrane can be developed for several common flexible gas storage configurations.
Double Membrane Gas Holder
A double membrane gas holder usually uses an inner gas membrane and an outer weather membrane. Air pressure between membranes helps maintain the outer shape while the inner membrane changes with gas volume.
Tank-Mounted Digester Cover
Installed on top of a digester tank, this solution combines gas storage and tank cover functions while reducing the need for a separate gas holder foundation.
Slab-Mounted Gas Holder
A standalone biogas storage system can be installed on a concrete slab or base, using membrane fabric as part of the gas storage envelope.
Biogas Dome
Biogas domes may use internal, external and bottom membranes. They are suitable for storage of biogas, carbon dioxide or other low-pressure gases.
Biogas Balloon
Biogas balloon systems require flexible, weldable and gas-tight fabric with strong seam reliability and stable long-term membrane behavior.
Single Membrane Holder
Single membrane holders are often used as tank cover solutions where the membrane must match tank geometry, gas pressure and local weather conditions.
Lagoon Biogas Cover
Floating or supported lagoon covers may use gas-tight membrane fabric for manure lagoons, anaerobic lagoons and covered lagoon biogas collection.
Industrial Gas Storage
Flexible membrane gas holders can be used in wastewater treatment, food waste digestion, agricultural biogas and industrial organic waste treatment.
OEM Gas Holder Systems
DERFLEX can support system builders and membrane fabricators with repeatable membrane material programs for different gas holder types.
Inner, Outer and Bottom Membrane: Material Roles
A high-performance biogas holder membrane page must explain the difference between each membrane layer, because each layer has a different engineering role.
Gas-Holding Layer
The inner membrane is in direct relationship with the biogas volume. It should prioritize low gas permeability, chemical resistance, flexibility, welding reliability and stable performance under pressure changes.
Weather-Protection Layer
The outer membrane forms the visible structure and protects the gas holder against UV, rain, wind, snow, temperature and outdoor aging. PVDF surface direction is often considered for premium outdoor durability.
Gas Dome / Base Layer
Some biogas dome or balloon systems use a bottom membrane as part of the storage envelope. It should be selected for gas tightness, mechanical strength, welding and foundation compatibility.
Technical Specifications for Biogas Holder Membrane
Final specifications should be confirmed according to gas holder type, storage volume, pressure range, wind / snow load, gas composition, welding method and project design.

Key Performance Advantages
DERFLEX designs biogas holder membrane fabric around real operating conditions: gas pressure, membrane movement, chemical vapor, outdoor exposure and fabrication quality.
Low Gas Permeability
Gas holder membranes can be developed with low gas permeability direction to reduce methane loss and support more stable gas storage operation.
High Tensile Strength
Reinforced base fabric helps the membrane resist pressure, wind load, tension, anchoring stress and repeated movement.
Strong Seam Compatibility
The coating surface can be designed for reliable welding and fabrication, helping fabricators build larger gas holder panels.
UV and Weather Resistance
Outdoor gas holder systems require fabric that resists sunlight, rain, temperature fluctuation and long-term weathering.
Chemical Resistance Direction
Biogas environments may include hydrogen sulfide, condensate and organic vapor, so membrane selection should consider chemical exposure.
PVDF Surface Option
A PVDF surface direction can be considered for outer membranes requiring better dirt resistance, surface durability and long-term appearance.
How to Choose the Right Biogas Holder Membrane
Correct material selection depends on the membrane layer, gas holder design and project environment—not only on thickness or price.
Choose by Membrane Layer
- Inner membrane: prioritize gas tightness, chemical resistance, flexibility and weldability.
- Outer membrane: prioritize UV resistance, tensile strength, weather resistance and surface durability.
- Bottom membrane: prioritize gas tightness, base compatibility, seam design and mechanical resistance.
- Tank cover membrane: consider tank diameter, anchoring, gas pressure and maintenance access.
- Biogas balloon membrane: consider folding behavior, pressure change and seam reliability.
Choose by Project Condition
- High H2S gas: review chemical resistance and surface protection direction.
- High UV location: consider enhanced UV formulation or PVDF surface direction.
- Cold climate: confirm low-temperature flexibility and welding behavior.
- Strong wind / snow: review tensile strength, tear strength and structural load assumptions.
- OEM repeat orders: standardize roll width, color, coating and inspection parameters.
